Concentrated, high-nitrogen fertilizer.
Compared with other nitrogen fertilizers, particularly ammonium
nitrate, urea contains the greatest amount of nitrogen in *6% of
the amide form, while *4% of nitrate nitrogen (ammonium form in
half and half in the nitrate), which determines the economic
feasibility of purchasing and use
of urea as the main fertilizer and foliar incorporation as a
solution for all crops and all types of soil.
Suitable for melamine, cyanuric acid, urea-formaldehyde resins,
pharmaceuticals, and as a component of cosmetic preparations, in
agriculture as the most concentrated nitrogen fertilizer (it
contains *6.2% nitrogen) for many crops in any soil, as an additive
to fodder for
ruminant animals.
Another important industrial application of urea synthesis is a
urea-aldehyde (especially urea-formaldehyde) resins are widely used
as algezivov in the production of wood-fiber board (MDF) and
furniture production.
Urea is produced in granular form, malogigroskopichen, nontoxic,
and storage of compressed slightly soluble in
water.
Carbamide
(urea) - CO (NH2) 2 - contains not less than *6%
nitrogen. Produced
by the synthesis of ammonia and carbon dioxide at high pressures
and temperatures. White
crystalline product, soluble in water. Hygroscopicity
urea at *0 ° C is relatively small. In
good storage conditions, little cake, preserves rasseivaemost
satisfactory. Especially
good physical properties are granulated
urea. Urea
is considered one of the most effective nitrogen
fertilizer. It
comes in two variants - A - for industrial use, and B - for
agricultural use. Urea
is used in medicine in the manufacture of drugs and
pharmaceuticals, as a component of resins and adhesives in the wood
processing industry. In
addition to fertilizers and glue, urea is synthesized from
herbicides - chemicals used to kill unwanted vegetation (all at a
certain location).
Carbamide
(urea) - a concentrated nitrogen fertilizer, easily soluble in
water and referring to the generic category.
The
main macro-urea and other nitrogen fertilizers actually nitrogen, a
chemical element is extremely important for a normal full life of
the plant. In
urea in terms of dry matter present in a concentration of
*6%. Element
is directly connected with the construction of biomolecules and
entree into the most important acids and
proteins. Thus,
nitrogen stimulates and promotes the growth of plants and
crops. After
the discovery of such a useful feature of the element it began to
actively use and implement in agricultural production agronomists,
making it possible to obtain with the limited land area much larger
yields of useful crops.
Carbamide
(urea) can be added to any type of soil. Nitrogen
improves the quality of fruit plants and fruits
themselves. If
the nitrogen in the soil is not enough, the tree branches become
thin and weak, less branched and the leaves become yellow in color
in the fall.And
the yellowing begins with lower leaves, as originally nitrogen from
domestic reserves of the plant, and it moves into the growth zone -
to younger leaves and fruit. However,
excess nitrogen is harmful to plants, since there is a more
vigorous plant growth, and the trunk and branches grow in the
ovaries of fruit damage. Therefore,
nitrogen fertilizers, particularly urea, it is necessary to make,
following the recommended doses, according to the possible methods
of bait: dissolved in water or in bulk, and then be
watered. Urea in the
soil is usually done in the spring.
